Clai'mspriority, application Germany May 10, 1954 8 Claims. (Cl. 51-3) The invention relates to a plant for cleaning, that is removing scale. or rust from wire or the like, by means of a plurality of [cleaning rollers of textile material, rubber or thelike arranged behind each other in the direction in which the who travels, which may follow crushing cylinders if; desired.

One of the objects of the invention is to provide an arrangement for removing scale from wire or the like in an improved manner.

In one aspect, the invention consists in providing several cleaning rollers operating one behind the other which are intercoupled in such a manner that they are rotated at different speeds by the pull exerted by the wire.

Rotation at diiierent speeds can be attained, for example, by connecting two successive cleaning rollers, on. the same or opposite sides of the material to be treated, by a chain thru the intermediary oi toothed rims with different. numbers of teeth.

At the same time, the two cleaning rolls, or possibly sets of cleaning rollers, can be mounted on the ends. of a two-armed rocker lever so as to act from opposite sides on the material to be treated.

Furthermore, it may be advantageous to couple such a. rocker lever with a carrier for one of two groups of cylinders liftabl'e from each other for the purpose of introducing the material laterally into a preceding tie-scaling unit, in such a manner that it is controlled by this group and is brought therewith into the working and introducing positions respectiveiy.

An extraordinary simplification of such an entire plant or apparatus results if the textile material cleaning device, together with the other stations serving for de-scaling or de-rusting the material, are all accommodated in a common, preferably mobile, housing.

At the same time, it is advisable that the entire housing which surrounds the textile cleaning device, in addition to the other stations serving for de-scaling or de-rusting the material, has an easily closable longitudinal slot in one of its longitudinal sides running parallel to the pulling direction of the material for introducing the wire or strip material in transverse direction, the slot extending into the end walls of the housing at least up to the inlet and outlet apertures for the material.

In a preferred form of construction the cleaning apparatus or plant consists of the textile cleaning combination together with the stations thru which the wire or strip material passes successively, comprising, for example, a crusher preferably composed of two groups of cylinders capable of moving apart, and a vertical, preferably tubular container widening towards its upper end for the reception of abrasive bodies, such as marcasite or the like. If desired, for example, a magnetic, electrostatic or similarly operating final cleaning device, can be included. These stations are arranged one after the other along the line of a loop so as to shorten the constructional length of the de-scaling plant and preferably standing in a vertical or substantially vertical plane with its ends preferably pointing in opposite directions.

" nited tates atent 2,788,616 Patented Apr. 16, 1957 Several embodiments of the invention are illustrated byway of example in the accompanying drawings, in which:

Fig. 1 is a. longitudinal section ofone form of construction of a cleaning plant for de-scaling and de-rusting wire or strip material;

Fig. Zis a sidedeviationof Fig. 1;.

Fig. 3 a perspective View;

Fig, 4 shows one form of the de-scaling rollers; and

Fig. 5 shows another form of support forthe rollers of Fig. 4.

According. to Figs. 1 to 3 a housing 2 is mounted on a mobile. platform I and the material 3' to be cleaned is passed through: the housing. along a looped path the two ends ofwhich are oppositely directed.

As can. be seen from Fig. 1, the wire or strip. material 3 runs over guide. rollers 4, then horizontally between crushing rollers 5,. then is guided over a guide roller 6 and runs vertically upwards thru. a container 7 filled with marcasite or the like. It then moves back down an incline over a second deflectingroller 8, thru scouring rollers 9" of. textile material. and thereafter passes around a third deflecting. roller 10,, to run. in a. horizontal direction thru a. magnetic, final. cleaningclevice. Ill and leaving the housing 2 between: guide rollers 12.

As can be: seen from the illustration, the material is firstroughcleaned by the. crusher cylinders 5 which loosen the scale, then. as it passes. thru the container 7 is fine scoured. by the abrading particles which are continually turned. over during the passage of the material. Thereupon: any dust or metallic particles which may still adhereto the metal. surface of the material. 3 to be cleaned are: removed by the-textile rollers 9 and finally magnetizable particles which have hitherto not been removed are. caught by the magnetic final cleaning device ii.

The new plant, which is much more compact than any plants hitherto onthe market, includes all the necessary stations, is mobile and in no way interferes with work being carried out in the neighbourhood, and delivers a material the surface of which is not only entirely free from any scale or rust but also from even the finest abrat' ing particles.

Fig. 2 shows that one of the longitudinal walls 13 has a longitudinal slot 14 easily closable, for example by strips of bristles, for the transverse insertion of the wire or strip material 3. The longitudinal slot 14, as can be seen from Fig. 3, extends into the end walls of the housing up to the inlet and outlet apertures 15 for the material.

The entire plant can easily be run to any desired place between a wire drum 16 and a winding device 17 whence the material is guided on to a winding drum l8 (Fig. 2).

Figs. 4 and 5 show forms of construction which the inventor has found most advantageous.

According to Fig. 4 textile rollers 22, composed of a plurality of separate textile disks built up in laminated form and tightly pressed together between two end wooden disks 21, are rotatable one on each of two dead journals 29 mounted on an equal-armed rocker lever 19.

The location of the lever pivot 23 is so chosen that as the equal-armed lever 1% swings out of a position at an angle of to the passing wire 3, the textile cleaning rollers 22 are brought to bear uniformly against the wire. Thru the intermediary of a loading weight 2d a uniform pressure is obtained. Both rollers 22 are provided with spur-wheels 25 with a different number of teeth and interconnected by a chain 26. Thus a differentiation of the circumferential speeds of these textile cleaning rollers 22 rela tively to each other and at the same time relatively to the speed of the wire 3 is attained so that a relative movement is produced which results in abrasive action being exerted on the surface of the wire by the textile cleaning rollers 22.

According to the form shown in Fig. 5 the textile cleaning rollers 27 are rotatably interconnected in pairs by chains from one arm of one of the levers 28 to the cor responding arm of the other lever 28.

A control rod 30, which engages a lifting carrier of one of the groups of crusher cylinders 5, ensures that in the wire inserting position, that is the zero position, the levers 28 stand at right angles to the running direction of the wire so that the wire can easily be introduced between the crusher cylinders 5 from the side. When said carrier of one group of cylinders 5 is lowered, the rollers 27 automatically bear aginst the wire 3 under the action of the loading weight.

In spite of the simplicity of this arrangement the cleaning effect obtained is extremely satisfactory.
